Pokemon X and Y will be launching the long awaited Pokemon Bank and Poke Teleporter in the Nintendo 3DS shop on December 27.

Requiring an Internet connection to use, the Bank will allow users to store up to 3,000 Pokemon spread over 100 boxes in a cloud based storage file. The Teleporter will let gamers bring in their older Pokemon from previous installments of the game, Black and White, and Black 2 and White 2.

GameSpot mentions that users can go even further back in the catalogue and transfer Pokemon from Diamond and Pearl, and HeartGold and SoulSilver to the Black and White games so they can then be teleported to X and Y since the older versions are not directly compatible with the new game.

From December 27 to January 31 2014, Pokemon Bank will be offering a free 30 day trial of the service, to which after that it will be $4.99 a year.

It is unclear what will happen if a user fails to pay the subscription, however, one can speculate the account will be suspended and the data will be held for an extended period of time until the user pays and it can be restored.

The Poke Transporter is a completely free app that will also be available in the 3DS eShop. This app will only work if used with Pokemon Bank.

This app will be the connection between the old games and the new one. Once a character is transferred from the DS games to X and Y it is final. There is no trading back to the older games.

"Whether you're preparing for competitive Pokémon battles or you've just gotta catch 'em all, Pokémon Bank is a powerful new tool for Kalos Trainers. Deposit, store, and manage your Pokémon in private Boxes and transfer them into your Pokémon X and Pokémon Y video games.
